Abstract :
In this paper, priority based distributed scheduling algorithm for mobile data gathering in Wireless sensor networks (WSN) is proposed. This proposed method involves data exchange policy to avoid dropping and then distributed scheduling algorithm for data gathering. Initially, the centralized algorithm places the polling points (PPs) on the shortest path. These polling points (PP) buffer locally aggregated data and upload the data to the mobile data collector when it arrives. The data is classified as high and low priority based on the deadline and urgency. At the second module, data exchange policy is processed and it is used in order to avoid dropping of higher priority data, data can be exchanged between two mobile data collectors. Finally in the distributed scheduling algorithm, the time slots are scheduled according to which the data collector could gather the maximal amount of data within a limited period. By simulation results, we show that the proposed algorithm minimizes the data losses and reduces energy consumption.
